The liquid-liquid fluidized heat exchanger described was operated with organic droplets particulately fluidized in an aqueous brine. The experimental work was conducted within the following range of operating conditions: voidage 60 to 97 percent, temperatures inside the heat exchanger 3-32C, and droplet sizes in the range of 2. 7 to 5. 8 multiplied by 10** minus **3 m. The effects of droplet size variation upon the eccentricity of the droplet, upon the terminal and slip velocities, and upon the thermal behavior were examined. The experimental flow characteristics were utilized in the evaluations of flow parameters employed in the analytical wake model. The predicted temperatures and heat transfer coefficients agreed well with the experimental values.
